Abstract (en)
[origin: WO02084019A1] A system for feeding fibres from a fibre separation step at a first pressure to a drying step at a second, lower pressure, the system comprising a sluice feeder (3) provided between the fibre separation step and the drying step. At least an outlet (14) of the sluice feeder (3) is enclosed by a housing (4) for pressurization by means of a pressure medium in the housing (4) to a pressure that essentially corresponds to the first pressure in the sluice feeder (3). The fed out fibre from the sluice feeder (3) to the housing (4) are removable by means of the pressure medium in the housing (4) via a control valve (20), which regulates the pressure in the housing (4), to the drying step at the second, lower pressure. The pressurization in the housing (4) prevents steam to escape from the sluice feeder (3). A method for feeding fibres, the fibres are fed to a sluice feeder (3) which is pressurized from the outside by means of a pressure medium and are fed out by means of the pressure medium via a pressure regulating control valve (20) to the drying step.
